,. anon-cum To allwhmnit'mwy concern: v Be it'known that I, HENRY J. Sonmrrz, a citizen of the United States, residing at Berkeley, in the county of Alameda, and State of California, have invented certain new and useful Improvements in Fruit-Cannets; and I do hereby declare the followmg to be a full, clear, and exact description of theQinvention, such as w1ll enable, others skilled in the art to 'whlch 1t appertalns to make and'use the same.

The present invention relates to lmprovements in fruit canners, and has for an ob ect toprovide an improved mach ne for insuring the delivery, of a predetermined number of ieces of fruit to each can 1n an automatic and reliable manner.

Another object of the inventionl es in providing an improved canning-mach ne 1n which a simple and inexpenswe device 1s employed to act in conjunctlon with a conveyor on which the cans are moved past a plura ity of chutes whereby a desired number of pieces of fruit may be delivered to each of the cans from the chutes so that when each can has traversed the entire number of chutes it will be made to contam a predetermined and uniform number of the pleces of fruit.

In the accompanying drawings forming a part of this application, and in wh1ch sumlar reference symbols indicate correspondmg parts in the several views:

, Figural is a side view of an improved canmng machine constructed in accordance resent invention,

Fig. 2 1s a top lan view thereof. Fig. 3 is an en arged cross sectlonal view through the same.

Fig. 4 is a fragmentary perspective v ew of one of the chutes and the fruit controlling device.

Fig. 5 is a similar view of one of the pickofl arms; and

Fig. 6 is a transverse sectional view throu h the chute. I Y Re erring more particularlyto the drawings, 1 designates a holder for the fruit m which isplaceda-shaker screen 2 to msure the delivery of the pieces of fruit to chutes 3 communicating .Wlth' the holder-1 at one side thereof near .its base, and being disposed in inclined. positions, to allowthe fruit to descendonto the, latform4 provided at the lower ends of eac of the chutes.

The chutes 3 are provided in any suitable Specification of Letters Patent. Patented A 1 1921; Application men say 25,1920. serial No. 384,100. A

movement of the fruit and prevent its accidentally sliding ofiz' the platform in case it should descend from the chute with too great force. 4

The cans to receive the fruit are designated at 6, and are supported on a. conveyer 7 of the endlessv type moving about sprocket wheels or drums 8 and 9 which are supported at an elevation by bearing stands 10 and 11. The conveyer 7 is provided with aplurality of pick-off arms 12 having horizontal base portions 13, riveted or otherwise se cured to the conveyer as indicated at 14. The base portions 13-extend to that side of the conveyer 7 next the chutes 3 so that the arm 12 extends at right angles from the conveyer belt and at one side thereof. As indicated 1n Flg. 1, the cans 6 are intended to be placed on the conveyer belt 7 just in advance of the arms 12 which controls the delivery of fruit thereto.

At their upper ends the arms 12 are provided with cross bars 15 extendin parallel with the base ortions 13 and over ying the conveyer belt The cross bars 15, are slot-- ted horizontally, as indicated at 16, to receive the platforms 4 of the chutes, a vertically disposed slot 17 being supplied at the inner end of the slot 16 of substantially the form of the turned u end 5 of each platform4 so that the pick-o device may pass in sequence through all of the platforms. A sweep 18 is left above the slot 16, and is so positioned and constructed as to wipe over the upper faces of the platforms 4 and push any pieces of fruit thereon into the openupper ends of the cans 6 which may immediately precede such sweeps;

As shownmore particularly in Fig. 4, each of'the chutes 3 is provided with a controltime to the platform 4. This device isshown in Figs. 3 and 4 as constructed to allow of two pieces resting on the platforms 4, al-

shaft, so that when the pin 23 projects directly downward and in the path of the pieces of fruit, the upper pin 22 w1llbe withdrawn from the fruit and W111 lie substantially parallel with the adjacent bar so as to permit the fruit to descend so far as is permitted by the lower pin 23. The pins 22 and 23, as shown, are spaced apart a distance corresponding to the width of two of the pieces of fruit, so that when in the position shown in Figs. 3 and 4 two of the pleces of fruit may descend past the upper pin 22,

where they will be held the lower part of the chute by the lower pin 23.

A coil spring 24 is wound about the rock shaft 19 between the bars 20 and 21, and has one end 25 thereof secured to said rock shaft while the other end 26 is affixed to the lower bar 21. The action of the spring 24 is to normally and yielding ly hold the parts in the position shown in igs. 3 and 4, while at the same time permitting of the oscillating movement of the shaft and the pins carried thereby.

A fin er 27 is formed integrally with or attacker? to the lower end of the rock shaft 19 and is bent down at a lower level than the platform 4 in order to be en aged by the arms 12 of the conveyer 7. he action is intended to be such that when any one of the arms 12 engages a finger 27 the rock shaft 19 will be swung in a'clockwise direction, looking out the lower end thereof an angular distance sufficient to withdraw the lower pin 23 from engagement w1th the pieces of fruit, thus allowing them to descend bygravity intothe platform 4; while at the same time bringin the upper pin 22 into engagement with t e pieces of fruit 1 ing above the same on the chute to prevent descent of the latter while the lower pin 23 is in the withdrawn position.

It will be apparent, therefore, that the de-.

vice will admit precisely two pieces of fruit to. the latform at each subsequent actuation. C dnsequently each can as 1t passes any particular chute will receive from the platform 4 thereof b means of the sweep 18, two such pieces of i uit, the controlling device immediately admitting a like number of subsequent pieces of ruit as soon as any particular can has passed the same.

The cans may be automatically delivered to the conveyer and automatically removed therefrom in any desired manner.

It is obvious that those skilled in the art mayvary the details of construction and arforms and adapted to carry containers therebeneath, and sweeps carried by said conveyer and being slotted to fitabout the platforms and said flanges, substantially as described.

2. In a fruit canner, a holder for the fruit, a plurality of chutes leading therefrom, platforms at the lower ends of the chutes, a conveyer passing beneath the platforms, sweeps carried by said conveyer for removing the fruit from the platforms, an arm carried by each chute in the path of the sweeps, and means controlled by said arm for regulating the quantity of fruit admitted to the platforms, substantially as described.

3. In a fruit canner, the combination of a holder for the fruit, a plurality of chutes inclining downwardly from the holder, platforms at the lower ends of the chutes, a rock shaft journaled longitudinally in the central portion of each chute near its lower end and having pins extending downwardly there- 'from at spaced points, said pins being disposed at substantially right angles, yieldable means for holding the lowermost pin in the path of the fruit descending the chute, a conveyer for carrying containers beneath the platforms, and sweep means carried by said conveyer and acting on said'rock shafts, to remove the lower pin from the path of the fruit and at the same time insert the upper pin in the path of such fruit, substantially as described.

4. In a fruit canner, a succession of platforms adapted to receive fruit, a conveyer having a number of receptacles thereon 'passing beneath the platforms, means carried by the conveyer for sweeping the fruit from the platforms into the receptacles, and means associated with the platforms and acted on by said last named means for controlling the delivery of fruit to the platforms in predetermined quantities, substantially as described.

5. In a fruit canner, a source of 'fruit supply, a number of inclined chutes leading therefrom, platforms at the lower ends of the chutes, means for controlling the delivery of the fruit from the chutes to the platforms, said means including a pair of offset pins spaced apart a distance corresponding to the giuantity of the fruit desired, said pins adapte to alternately engage the fruit, means whereby the lower pm may be normally and yieldingly held in engagement with the fruit, a conveyer adapted to bring a series of cans successively beneath the platforms, means for* sweeping the fruit from the platforms into the cans, and a device acted on by said last named means for withdrawing the lower pin from the fruit to allow of the delivery of subsequent pieces to the platform and at the same time inserting the upper pin in the path of the fruit, substantially as described.

6. In a fruit canner, the combination of a holder for the fruit, a number of chutes leading from the holder, a shaker screen in the holder for delivering the fruit to the chutes, platforms at the lower ends of the chutes, an endless conveyer operating beneath the platforms and adapted to carry cans therebeneath, sweeps carried by said conveyer for brushing the fruit from the platforms in the cans, and means in the lower ends of the chutes adjacent the platforms for regulating the number of pieces of fruit to be delivered to the platform and acted on by said sweep means for automatically permitting of the delivery of fruit to the platforms, substantially as described.
